Siamese sable can also look like chocolates when newborn but because you've got REW (or himi) in the litter and both parents are full colour, sable is not genetically possible :cheesysmile:
My Standard Rex litter (with the chocolate) are now 4 weeks old, I thought I'd post an updated picture.
1 x Chocolate
3 x Black otter
3 x Himalayan
1 x Rew
